Drawings for Powerball are held every Wednesday and Saturday evening at 10:59 p.m. Eastern Time. Since October 7, 2015, the game has used a 5/69 (white balls) + 1/26 (Powerballs) matrix from which winning numbers are chosen, resulting in odds of 1 in 292,201,338 of winning a jackpot per play.[1] Each play costs $2, or $3 with the Power Play option. (Originally, Powerball plays cost $1; when PowerPlay began, such games were $2.) The official cutoff for ticket sales is 10:00 p.m. Eastern Time; some lotteries cut off sales earlier.[2] The drawings are usually held at the Florida Lottery’s studio in Tallahassee.


Assuming that you have chosen an online lottery company that physically purchases tickets online. How you play Powerball online is the following; Firstly, pick whether you want to buy group Powerball tickets online or single tickets. Almost all online lottery ticket providers offer the player to buy group tickets in addition to single ticket purchases. An online group game ticket in the Powerball is the same concept as a work syndication for the lottery, only nowadays thanks to the wonders of the internet, you don’t have to rely on the people in your vicinity – you can join a syndicate that is made up of hundreds, if not thousands of people scattered all across the globe. 
Generally, Powerball players do not have to choose cash or annuity unless they win a jackpot (then they usually have 60 days to choose.) Exceptions include Florida and Missouri; the 60-day "clock" starts with the drawing, so a jackpot winner who wishes to take the cash option needs to make immediate plans to claim their prize. New Jersey and Texas require the cash/annuity choice to be made when playing; in New Jersey, an annuity ticket can be changed to cash after winning, while in Texas, the choice is binding (when the cash option was introduced in 1997, all Powerball players had to make the choice when playing. This regulation was phased out by 1999.) All Powerball prizes must be claimed within a period ranging from 90 days to a year, depending on where the ticket was bought.
Michael Sweeney, executive director of the Massachusetts State Lottery, apologized Thursday afternoon for the mix-up, saying it was the result of a “human error” but added that the lottery’s internal systems always had the correct information. He said those internal systems ran a routine report in the morning identifying Chicopee as the correct location, and lottery officials then checked to ensure that it was accurate.
Hot numbers are the lottery numbers that appear the most, and US Powerball's all-time hot numbers are 26, 16, 41, 32, and 28. Cold numbers are the numbers that appear infrequently. Some lotto fans choose them specifically because of this, believing that their reappearance in US Powerball results is only a matter of time, while others stay clear. The US Powerball lottery all-time cold numbers are 60, 65, 67, 68, and 66. We update Powerball’s hot and cold numbers listings every year to help you make your number selection.
If you do find yourself at 11 p.m. ET Tuesday with the winning ticket in your hands, be prepared to keep quiet after that initial scream of joy to your spouse or other loved one, said certified public accountant Daniel Mahler of Gisler & Mahler in Bloomingdale, N.J. And sign your ticket; that establishes it as yours before you go to the nearest lottery office to claim your prize.
The two different methods, both offer you, the player, the same user experience and the only difference is in the back end of how the online lottery ticket provider works. The two methods that online lottery sites use differ in one key way; They either have agents and employees all over the world that physically purchase tickets on behalf of clients or, the more recent phenomenon is when companies essentially take out an insurance policy on every ticket which is tied to the size of the jackpot. This is the difference between you playing the lottery online and betting on the lottery online*. In the latter option you are, de facto, not playing the US Powerball online but rather you are placing a bet with an insurance company on the outcome of the corresponding Powerball draw.
